HELP all games fail d2pro

used verbatim dvd's at 4X and now at 1X burn. all games used to work until i burnt monopoly which did not work. now all the games i try do not work. keeps either saying error when playing game (5mins into it) or a straight up error where disk is not read and have to restart the console because of black screen telling me to do so

please help, i am very stuck, i can hear the drive prower up, and then stop and this is when the disk is not read. i donot know what is the problem
